United States Patent HOLDERS AND OPENERS FOR HAIRPINS Roman Zipperlin, Belleville, N. J.

Application October 26, 1954, Serial No. 464,787

2 Claims. (Cl. 132-1) My invention relates to improvements in holders and openers for conventional bobby pins of commerce and is designed as an improvement over the pin holder and opener of my copending application, Serial No. 462,219, filed October 14, 1954, now abandoned.

The primary object of my invention is to provide a portable device for use on a vanity, dresser or the like to hold a plurality of such pins in side-by-side closed substantially horizontal position and which embodies a rotary blade for opening all the pins simultaneously by flexing one leg of the pins upwardly.

Another object is to provide a device for the purpose and operative as above set forth and which will not injure the pins, and is durable and adapted for economical manufacture.

Other and subordinate objects, together with the precise nature of my improvements will become apparent when the following description and appended claims are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Figure 1 is a perspective view of my improved holder and opener;

Figure 2 is an enlarged view in vertical transverse section taken on the line 22 of Figure 1;

Figure 3 is a view similar to Figure 2 with the opener blade rotated to open the pins;

Figure 4 is an enlarged fragmentary view in horizontal section taken on the line 44 of Figure 1;

Figure 5 is an exploded enlarged view in perspective, partly in section, of parts of the holder disassembled and parts rotated 90 from their normal position relative to other parts; and

Figure 6 is an enlarged fragmentary view in horizontal section taken on the line 66 of Figure 1.

Referring to the drawings by numerals, my improved holder and opener comprises a rectangular base tray 1 having at the ends and rear corners thereof a pair of laterally spaced left and right uprights 3, 5, the uprights 3, 5 being provided with a pair of upper ends 7, 9 extending forwardly over the tray.

A pin opening blade 11 extends horizontally between said ends 7, 9 and is rotatably mounted thereon by a pair of lateral, left and right end ears 12, 13 rotatably fitting in confronting recesses 15, 17 in said ends 7, 9 and provided with left and right trunnions 19, 21 journaled horizontally in a pair of horizontally aligned openings 23, 25 in said ends 7, 9.

An operating crank arm 27 for said opening blade 11 is non-rotatably mounted on the right trunnion 21 outwardly of the right upright 5 by means of a flat sided hole 29 in one end of the crank arm 27 fitting on a flat sided terminal portion 31 of said trunnion 21.

A rectangular pin holding blade 32 extends substantially horizontally in front of the pin opening blade 11 at a slight downward and forward inclination and is mounted by a pair of left and right apertured cars 33, 35 on the left and right trunnions 19, 21 with the pair of cars 33,

2,777,450 Patented Jan. 15, 1957 2 r 35 straddling the upper ends 7, 9 of the uprights 35 and the right ear 35 interposed between the upper end 9 of the right upright 5 and the operating crank arm 27.

A lateral key lug 37 on the right ear 35 of the pin holding blade 32 seating in a notch 39 in the upper end of the right upright 5 locks said blade 32 against rotation on said trunnions 19, 21.

As best shown in Figures 2 and 3, the ears 12, 13 and trunnions 19, 21 of the pin opening blade 11 provide for rotation of said blade 11 clockwise as viewed in Figure 2 about a relatively offset axis into a normal idle position in which it is susbtantially horizontal and coplanar with the holding blade 32 and forms a rear extension thereof, and said opening blade 11 is rotatable in the opposite direction, that is, counter-clockwise as viewed in Figure 3, from its normal position into a substantially vertical pin opening position in which it extends above the rear edge of the holding blade 32. 7

in rotation of the opening blade, the ears 12, 13 thereof coact with the recesses 15, 17 to limit rotation of said blade and establish the normal and the pin opening position of said opening blade.

In using and operating the device, the opening blade is rotated into normal position as shown in Figures 1, 2, 4 and 6, and a bobby pin, for instance, the one illustrated at 41, is shoved rearwardly onto said holding blade 32 into straddling relation to both blades to grip said blades by the resiliency of the legs thereof, the crimped leg 43 uppermost. This obviously positions the crimped leg 43 above said blades 11, 32. The opening blade 11 is now rotated into vertical pin opening position between the legs 43 of the bobby pin 41, as shown in Figure 3, flexes the uppermost leg upwardly and opens and holds said pin open for insertion of a finger between the legs 43 to pull said pin forwardly off said blades 11, 32.

A longitudinal front edge rib 45 may be provided on the holding blade 32 for gripping by the loop end 47 of a bobby pin 41 and a pressed up rear longitudinal edge rib 49 may be also provided on said blade 32 for snap action interfitting with one of the crimps 51 in the uppermost leg 43 whereby to retain the bobby pin on said holding blade 32. The tray 1, of course, is for pin stor-.

ing purposes.

The foregoing will suffice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention is susceptible of modification without departing from the inventive concept and right is herein reserved to such as fall within the scope of the appended claims.

What I claim as new is:

1. A holder and opener for hair pins having a pair of resilient legs comprising a base, a pair of laterally spaced uprights rising from said base, a rectangular rigidly mounted pin holding blade extending substantially horizontally across said uprights' and having front and rear edges, and a pin opening blade extending along the rear edge of said holding blade and having end trunnions journaled in said uprights and rotatably mounting said opening blade for rotation into horizontal and vertical positions, respectively, said holding blade and the opening blade when in horizontal position being adapted for straddling by the legs of hair pins shoved rearwardly onto said holding blade, said opening blade when rotated into vertical position flexing one leg of the hair pins away from the other to open said pins, and a crank arm on one of said trunnions for rotating said opening blade, said opening blade having lateral end ears fixed to said trunnions and offsetting said opening blade from said trunnions for rotation about an offset axis whereby to facilitate flexing one leg of said pins away from the other leg.

2. A holder and opener for hair pins having a pair of resilient legs comprising a base, a pair of laterally spaced uprights rising from said base, a rectangular rigidly mounted pin holding blade extending substantially horizontally across said uprights and having front and rear edges, and a pin opening blade extending along the rear edge of said holding blade and having end trn nnions straddling by the legs of hair pins shoved rearwardly onto said holding blade, said opening blade when rotated in vertical position flexing one leg of the hair pins away from the other to open said pins, and a crank arm on one ofi said trunnions for rotating said opening blade, said holding blade having apertured ears through which the trunnions extend and having a key and notch connection with one upright whereby to rigidly mount said holding blade.
